LORENTZ PS150 Boost provides city water pressure, anywhere. It has been a standard in home renewable energy systems since 1986. It is economical for domestic water supply, drip irrigation and water purification. Use solar-electric power to provide 250 to 10,000 litres per day from shallow water sources. PS150 Boost can push water as high as 140 m.

For 12 V to 24 V systems (1-2 solar modules or batteries in series) uses only one and the same motor and controller for solar direct or battery systems. Same flow at 12 V or 24 V.

LORENTZ PS150 Boost is not submersible, but can draw water from shallow wells, springs, cisterns, tanks, ponds, rivers and streams and push it through miles of pipeline. Slow pumping minimizes the size and cost of the solar array-battery system, wire and piping.

LORENTZ PS150 Boost is more powerful, quieter and much more durable than plastic RV/Marine pumps. It is less expensive than submersible DC pumps. Wearing parts typically last 5 to 10 years. Overall life expectancy is 15 to 20 years.

Suction Capacity

5 m (15 ft) at sea level. Subtract 1 m (3 ft) for every 1,000 m (3,300 ft) altitude. Pump should be placed as low and as close as possible to the water source. Suction capacity my be further limited by intake pipe friction (or clogged filter).

Intake piping should be 1” or larger.

Filtration Requirement

This pump cannot tolerate dirt. Water must be filtered clear. If water is very dirty, improve the source or consider a different pump.

PV-Direct (non-battery) Requirements

The rated power of the PV array must exceed pump watts by 20 % or more.

A linear current booster incl MPPT (maximum power point tracking) is already included !
